There are about 10004 clinical studies being (or have been) conducted in Brazil. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Type 2 diabetes mellitus (T2DM) leads to a high burden of morbidity and mortality, usually attributable to cardiovascular (CVD) causes. A major concern about the disease is that the success of the treatment is highly dependent on self-management, which very often incurs the necessity of behavior change. However, modifying such behaviors, usually linked to daily-life activities, is challenging. Then, the investigators aimed to test the optimal self-management that could be achieved in a reasonable manner carried forward through the Prochaska and DiClemente behavior-changing strategy in a follow-up of 18 months, compared to usual care. Our primary outcome is the between-group difference in HbA1c (%) levels.
The purpose of the D4325C00007 study is to identify and characterise patients with known or newly diagnosed CKD for possible participation in future renal clinical studies and to obtain an overview on current treatment choices for this patient group in different regions.
A paucity of prognostic studies in patients with post-COVID-19 syndrome (long-COVID) shows the need to identify the main effects on functional capacity in the short and medium term. In this regard, the evaluation of lung function, lung structure and functional capacity in long-COVID patients is essential to estimate the impact of the disease. This retrospective observational study aims to compare functional capacity, lung function, and lung ultrasound findings in patients who underwent physical therapy to those who did not.
This study aims to develop a digitally assisted telemonitoring platform using the Samsung TM Galaxy Watch5 smartwatch, validating the applicability of the solution in patients with POAF (Postoperative Atrial Fibrillation), along with the accuracy of the smartwatch in detecting vital signs through optical sensors and possibly identifying irregularities in heart rhythm. The validation of its applicability will be carried out through a clinical trial. This is a randomized observational pilot study resulting from the partnership established in the base year of 2022 between InCor and Samsung. The sample consisted of 108 outpatient patients with cardiac diseases who underwent cardiac surgery and were selected during the preoperative consultation. Subsequently, the patients were randomized (1:1) into the intervention group (teleassisted group) or the control group (standard institution follow-up). The sample size was proposed by the contracting party as this is a pilot study to assess whether the implementation of a technological solution assists in monitoring and predicting the risk of surgical patients in the postoperative phase, as well as the accuracy of the Samsung TM Galaxy Watch5 smartwatch in a sample with POAF.
The goal of this randomized controlled clinical trial is to compare effects of non-invasive ventilation with different modalities (notably CPAP and BIPAP) in patients undergoing heart surgery. The main question[s] it aims to answer are: - Which NIV ventilation mode is most effective in cardiac surgery patients? - Is there a big difference between conventional physiotherapy treatment and the use of NIV in these patients? Participants will be submited in the intervention will initially take place in the specific ward that receives patients in the postoperative period of cardiac surgery. Participants will be recruited after the patient is hospitalized the day before the surgery, during which time he will undergo a preoperative evaluation based on the study criteria. On that first day, the evaluation will consist of anamnesis and physical examination, focusing on the history of cardiac disorders, followed by measurements inherent to the protocol. Manovacuometry, chest X-ray, quality of life questionnaire, walk test and spirometry. The evaluation can be carried out in two stages, if there are other demands for the patient during his hospitalization. Researchers will compare three groups: 1 - cpap group - CPAP + usual physical therapy care, 2 - Bipap group - BIPAP + usual physical therapy care and 3 - Control - usual physical therapy care), in the 1:1 allocation ratio and superiority. to see if the effects of non-invasive ventilation with different modalities in patients undergoing cardiac surgery demonstrates some superior way in clinical practice. The observed outcomes will be: evaluation between NIV modalities, spirometry, lung capacity and vital signs. Secondary outcomes included are degree of satisfaction with the global perception of change scale, and MIF - functional independence measure and blood gas parameters.
The significant increase in the prevalence of obesity can also be attributed to various social changes, in which the environment (political, economic, social, cultural), and not only the individual and his choices, takes a strategic place in the analysis of the problem and proposed interventions. The food environment can influence the choice and consumption of foods that promote obesity, such as ultra-processed foods (UPA). It is suggested that to intervene to effectively change behavior and eating habits, intensive interventions are needed that consider multiple levels that include the family, school, and community rather than one-off interventions that may not be effective in changing behavior and lifestyle. Regarding the family environment, parents or guardians can assist in the adoption of obesity-related behavioral patterns. It is known that the context of Primary Health Care (PHC) is ideal for actions to prevent diseases and promote children's health, since the PHC professional team is closest to the reality of life of the child, family, and community. We emphasize the importance of this study from the perspective of treatment of childhood obesity, in order to generate scientific evidence and practical subsidies for the implementation of interventions focused not only on the individual, but also in the context of the Unified Health System (SUS). The hypothesis of the study is that there will be a decrease in the consumption of ultra-processed foods (UPA) among children, aged 6 to 10 years, living with obesity and who are treated in primary health care. In addition to encouraging healthy habits such as physical activity and the consumption of in natura and minimally processed foods. The management of childhood obesity is one of the priority topics on the national agenda of SUS's food, nutrition, and health promotion policies.
This study will investigate the clinical performance of a novel restorative glass ionomer (DeltaFil, DMG) in comparison to an established restorative glass ionomer (Riva Self Cure HV, SDI) in the restoration of Class II cavities in primary molars.
The goal of this clinical trial Is conducted to evaluate the efficacy and safety of active or sham HD-tDCS in combination with dexmedetomidine in patients with moderate to severe ARDS due to COVID-19 with delirium in intensive care unit (ICU). The hypothesis was that HD-tDCS combined with concomitant dexmedetomidine would reduce delirium rates.
Fibromyalgia is a syndrome characterized by chronic generalized musculoskeletal pain, accompanied by other symptoms such as fatigue, sleep disturbance and depression. Complaints of memory deficit, cognitive dysfunction, headache and gastrointestinal disorders are also common. Although it is a relatively common syndrome, exist a limited effectiveness of the pharmacologycal treatment. However, In the last years new therapeutic and diagnostic options have been sought. This scenario includes the use of different techniques of non-invasive brain stimulation, such as transcranial direct current magnetic stimulation (tDCS) and transcranial magnetic stimulation (TMS), which have already had promising results in reducing pain. Based on the above, the objective of this research is to evaluate the effect of cerebellar tDCS on clinical measures of pain and cortical excitability in patients with fibromyalgia. In this study, the intervention consists of a single tDCS session in which two devices will be used simultaneously. The active electrode will be placed in the cerebellum and/or in the primary motor cortex and the cathode in the contralateral supraorbital region. It is expected that the application of this protocol will be able to have a modulatory effect on clinical pain measures. In addition to producing changes in cortical excitability as a reflection of the integration between the cerebellum-thalamus-cortical pathways.
Studies with quantitative electroencephalogram (qEEG) in people with fibromyalgia showed the existence of distinct patterns of brain electrical activity when compared to healthy individuals. Such dysfunctional patterns may be correlated to clinical symptoms of the syndrome as chronic pain and emotional disorders (depression and anxiety). As chronic pain can be considered a multidimensional symptom, its evaluation should consider beyond others, two main dimensions: the sensitive-discriminative dimension and the affective-motivational dimension. Previous studies have been describing distinct brain areas as neural substrates for processing such dimensions of pain. Thus, the identification of electrophysiological biomarkers (i.e., as qEEG measures) allowing to perform an evaluation between dysfunctional patterns of brain electrical activity and different dimensions of pain seems to be a promising path in the search for a better understanding of the syndrome as well as for more individualized and effective therapeutic approaches. Our objective was to investigate whether dysfunctional patterns of brain electrical activity in frontal and central areas of people with fibromyalgia are differently related to dimensions of pain (sensory-discriminative and affective-motivational) and to emotional disorders (depression and anxiety).
